Title:
CLOSED-LOOP PHOSPHATIZING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO2000032842
Kind Code:
A9
Abstract:
A phosphatizing system for phosphatizing an object including a closed-loop phosphatizing assembly is provided configured to pass a phosphatizing reagent solution over an object during a phosphatizing procedure. The phosphatizing assembly includes a collection compartment in fluid communication with a run-off portion of a subfloor assembly supporting the object for receipt of substantially all the reagent run-off fluids from the subfloor assembly. A storage assembly is configured to pass a rinsing solution over the object to wash the reagent solution therefrom during a finishing rinse procedure performed after the phosphatizing procedure. This storage assembly includes a storage compartment in fluid communication with the run-off portion for receipt of substantially all the rinsing/reagent run-off fluids from the subfloor assembly. A fill pump, in fluid communication between the collection compartment and the storage compartment, is provided to transfer rinsing/reagent run-off fluids collected in the storage compartment to the collection compartment when the reagent solution contained therein drops below a predetermined operational fluid level.
